Whakamahia
He hua whakaū mārama tēnei, he pai te mahi, ka taea te mimiti i te hihi UV o te roangaru 240-340 nm me ngā āhuatanga o te tae mārama, kāore he paitini, he pai te hototahi, he iti te nekeneke, he ngāwari te tukatuka me ētahi atu. Ka taea e ia te tiaki i te polymer ki tōna taumata teitei, ka āwhina ki te whakaiti i te tae. Ka taea hoki e ia te whakaroa i te kōwhai me te aukati i te ngaronga o tana mahi tinana. He whānuitia te whakamahinga ki te PE, PVC, PP, PS, PC organic glass, muka polypropylene, ethylene-vinyl acetate me ētahi atu. Heoi anō, he tino pai te pānga o tōna pumau mārama ki te whakamaroke i te phenol aldehyde, te wanihi o te waipiro me te acname, polyurethane, acrylate, expoxnamee me ētahi atu.
